TOUCH® Prosthesis for Thumb Carpometacarpal Joint Osteoarthritis: A Prospective Case Series

Abstract

The dual mobility concept currently represents the newest generation of thumb carpometacarpal prostheses. The aim of this study was to evaluate the short-term outcomes of TOUCH® prosthesis. From September 2019 to July 2020, 40 prosthesis were implanted in 37 patients suffering from symptomatic stage III osteoarthritis. All included patients with a median age of 57.7 (IQR: 13.6) finished the systematic follow-up regimen (4, 8, 16 weeks, 6, and 12 months postoperatively). All parameters significantly improved (p < 0.0001) compared to the preoperative status. At 1 year follow-up, median DASH Scores decreased from 54 (IQR 22) to 12 (IQR 28) and pain levels improved from 8 (IQR 2) to 1 (IQR 2). Moreover, key-pinch strength increased from 3.8 (2.0) to 5.8 (2.5), while palmar abduction, radial abduction, and opposition also significantly improved. 35/37 patients were satisfied with the functional outcomes. We observed 10 complications, of which 6 were tendon-related issues, and 2 were due to an inappropriate choice of neck size. We could detect one dislocation but no evidence of cup loosening, tilting or subsidence in any patient. Despite the occurrence of some complications, we recommend implantation of this prosthesis type due to favorable clinical and radiological performance.

Trapeziometacarpal Joint Arthroplasty, a Salvage Technique for Failed Open Reduction Internal Fixation of the First Metacarpal

“…Articular fractures of the first metacarpal base are commonly treated with osteosynthesis. 8 However, failures of osteosynthesis are challenging and difficult to manage and may carry a risk of posttraumatic arthritis. In the presented clinical case, the failure of a primary ORIF resulted in stiffness, pain, and loss of function of the thumb in a young, active patient.…”

“…The implant of TMC prosthesis (TOUCH) was advocated as a salvage treatment for this patient. Trapeziometacarpal implants have been successfully used for cases of osteoarthritis of the thumb base, 7 , 8 although there is a lack of reports in the literature on the use of prostheses after fracture and osteosynthesis failure. After a search of the literature, we only found 1 report on the use of another implant (MAIA, LEDA Orthopaedics Ltd) for a patient with an acute intra-articular fracture of the first metacarpal.…”

“… 1 Although spacers seem to be more anatomical, the dual-mobility design of the ball-and-socket prosthesis allows for better restoration of the functional ability, which also increases joint stability. 7 , 8 To date, to our knowledge, there are no reports on the use of TMC arthroplasty after failure of open reduction internal fixation (ORIF) of an articular fracture of the first metacarpal base. This report aims to describe a case where a TMC dual-mobility prosthesis (TOUCH, Kerimedical) was implanted after the failure of ORIF of a previous articular fracture.…”

Arthroscopy-assisted partial trapeziectomy combined with ligament reconstruction for thumb carpometacarpal joint osteoarthritis: A different technique

“…At the last follow-up visit before summary, the pain intensity was evaluated on a visual analog scale (VAS) ( 12 ) from 0 (no pain) to 10 (worst imaginable pain). The ability to carry out daily life activities was evaluated based on the quick disabilities of the arm, shoulder, and hand (Quick-DASH) ( 13 ) questionnaire.…”

Conjoined Free Fibula Transplantation and First Carpometacarpal Joint Prosthesis for Functional Thumb Reconstruction—A Case Report

“…20,28 Numerous prostheses for the treatment of CMC-1 reconstruction are currently commercially available and pursue the goals to achieve satisfactory pain relief, improve key-pinch strength, maintain motion, prevent thumb shortening, and keep the postoperative recovery time short. 29,30 Pyrocarbon implants are used for hemiarthroplasties or interpositions. Hemiarthroplasties are metacarpal implants stabilized by an intramedullary stem, such as PyroHemispher, Carpometacarpal (CMI), Nugrip, or Saddle.…”
